Ice-CREAM DIPPER.

Patented 1, 1906.

Ton/ll whom it may concern:

Be it known that I, ALBERT P. OLMSTEAD, a citizen of the United States, residing at Watervliet, county of Albany, and State of New York, have invented certain new and useful Improvements in Ice-Cream Dippers,

e following is a specification.

The invention relates to such improvemerits; and it consists of the novel construc tlonand combination of arts hereinafter described and subsequent y claimed.

Reference may be had to the accompanying drawings and 'the reference characters marked thereon, which form apart of this specification. .Similar characters refer to similar parts in the several-figures therein.

Figure 1 of the drawings is a view in side elevation, tpartly broken away and partly in section, -0 my improved ice-cream dipper. Fig. 2 is a horizontal section of the same,

' taken on broken line 2 2 in Fig. 1. Fi 3 is a central vertical longitudinal section ta on on the broken line 3 3 in Fig. 2. Fig. 4 is a view in side elevation of the scraper detached.

The principal object of the invention is to provide an easily-operated and sanitary dipper for use in serving ice-cream and other plastic substances.

Referring to the drawings,.wherein the invention is shown in its preferred form, 1 is the handle, and 2 is the bowl of the dipper. The bowl may be of any desired form, circular in cross-section, that .shown inthe drawings being conical in form. The handle projects per endicularly to the axis of the bowl.

he bowl and handle are shown made of a single piece of metal; but they can be made separate from each other and secured together in any known manner to form a substantially integral structure.

Located within the bowl is a rotary scraper 3, comprising a strlilp ofsheet metal bent to conform substantia y tothe'shape of the interior of the bowl, sa1d scraper being fixedly upon a hub 4, rotatably mounted in a bearing 5 at the apex of the bowl. The hub is provided with ear-teeth 6, adapted to mesh with the teet of a ear-rack 7 on the end of a lever 8, fulcrume upon the handle at 9 and adapted to play in the slot 10 in the handle, which slot communicateswith the hub-bearing at the apex of the bowl to permit the meshing of the teeth on said hub and gear-rack, respectively. The hub 4 is formed filling the bowl.

with a peripheral flange 1 1, overhanging the gear-teeth thereon and adapted in the normal position ofthe lever 8 to overhang the teeth on the gear-rack 7, whereby said gearrack serves as a means for locking the hub within its bearing as well as a means for rotatin said-hub and scraper. The lever 8 is rovified with a thumbiece 12, ada ted to e engaged by the thum of the ban of the o erator which grasps the handle in using t e device, whereby said lever can be positively operated in one direction against the force of the spring 13, which operates the lever in'the opposite direction when the thumbpressure is released.

In using the dipper the handle is grasped by the hand of the o erator and the bowl is passed through the ody of ice-cream or other plastic material to be served, thereby The dipper is then held with the bowl over the plate, glass, or other receptacle in which the material is to be served and the lever 8 is operated alternately by the thumb of the operator and the spring 13 to cause rotative movements of the hub 4 and scra er 3, whereby the contents of the bowl are oosened and freed from the walls thereof and ermitted to fall by gravity into said receptac e.

The fulcrum-bearing for the lever 8 is formed by a thumb-screw 14, having a contracted end portion 15, which extends through a longitudinal slot 16 in the lever,

said screw having a threaded shank fitting a screw-threaded aperture in the upper part of the handle and terminating in a shoulder ada ted to fit a countersink 19 in the lever 8. at the outer end of the. slot 16. When the screw 14 is fully inserted, its said shoulder is located withinthe countersink 19, preventing a longitudinal movement of the lever 8 and maintaining said lever with its gear-rack and in position to lock the hub within its bearing, as above described. When it is desired to remove the scraper, as is donein.

cleaning the dipper, the screw 14 is loosened 'sufliciently to withdraw its shoulder from the countersink 19, whereu on the lever 8 can be forced outwardly to t e position indi-- cated by dotted lines in Fig. 2 to disen age itsgear-rack from the hub 4, thereby re easing said hub and the scraper mounted thereupon and permitting the same to be remeved in engagement with the gear-teeth on the hub 1 3: is sov placed as to oppose the outward nt of the lever8, as Well as the thin movement thereof, thus serving With the sera' oer-hui, release of the scr per and hub.
